摘要： A process for pickling and pretanning raw hides which comprises (I), pickling a raw hide in an aqueous liquor A which is devoid of salts and contains (a) a reaction product of phenol and a sulfonating agent, the molar ratio of (phenol):(SO.sub.3) being (1):(1.1-2.2), and (II), pretanning the pickled raw hide in the same bath by addition of an aqueous formulation B comprising (b) a reductive saccharide having a dextrose equivalent of 10 to 100, and (c) an aliphatic dialdehyde containing 2 to 8 carbon atoms. The combined one-bath pickling/pretanning process makes it possible to prepare, in treatment baths free from neutral salts and heavy metals, readily shaveable wet white leathers that are suitable for further processing by all conventional tanning methods.

摘要： Method of chrome tanning wherein, after unhairing and bating, a water soluble amino compound is provided in an acidified hide stock solution prior to or simultaneously with addition of a chrome tanning agent. The amount of chrome tanning agent required in the charge, and therefore the amount of chrome in the exhaust liquor or effluent, is thereby substantially reduced, thus providing greater control over pollution due to chrome in leather manufacturing operations.

摘要： Mineral tanned leather is frequently retanned with synthetic tanning agents to improve the fullness and softness, but leather retanned by the prior art methods is difficult to dye in full shades with anionic dyes. According to the invention, condensation products of C.sub.1-4 aldehydes with certain aromatic sulfonic acids or carboxylic acids containing amino groups are employed for retanning, thereby improving the receptivity of the leather for anionic dyes. These acids have the general formula ##STR1## where X and X' are independently H, --CH.sub.2 --SO.sub.3 H or --CH.sub.2 --OH, A is a benzene radical, Y and Z are independently H, --SO.sub.3 H or --CO.sub.2 H, R is H or C.sub.1-4 -alkyl and n is from 0 to 10, with the proviso that at least one sulfonic acid or carboxyl group is present in the molecule.

摘要： Transplants, particularly from pigskin, from humans, and amniotic membranes of newborns are prepared from the appropriate tissue -- which tissue is treated with the compound glutaraldehyde (GA).The so treated tissue excels by favorable biological function: increased resistance to infection, markedly reduced antigenicity, and prolonged retention time on the recipient, as well as the possibility to store so treated tissue for a prolonged span of time.
